Don’t sacrifice long-term weatherability for appearance. You can choose any color in a variety of textures and be confident for decades with acrylic capstocks.

SOLARKOTE™ acrylic capstock is applied during the profile manufacturing process, resulting in a chemically bonded composite part, not just a coating or laminated film. For this reason, capstock has superior durability when compared to painted surfaces.

SOLARKOTE™ capstock provides many benefits such as: best-in-class outdoor weatherability, aesthetics, low-heat build, and long-term durability.

Top 6 Reasons Manufacturers & Consumers Trust Acrylic Capstocks:
Acrylic capstocks provide an additional layer of protection against environmental factors like weathering due to UV radiation, moisture, and temperature fluctuations, which can degrade materials over time.
Dark colored capstocks with low heat-build performance play an important role in providing desired Heat Build Up (HBU), especially critical for vinyl windows.
Acrylic capstocks can enhance the aesthetic qualities of window profiles, offering options for different finishes like gloss or matte, with best-in-class weatherability ensuring the color does not fade over time.
Coextruded acrylic capstocks act as a protective barrier, making the frames more resistant to scratches and minor impacts, without the need for protective films, or other post-processing steps.
The low processing temperature of PVC poses no issue for acrylics. Both materials can be processed at similar temperatures, simplifying and facilitating coextrusion.
By coextruding, manufacturers can achieve the above benefits in a single manufacturing step, with low equipment footprint, no need for additional adhesives or primers, reducing production costs and time, and with high process yields and minimal waste.

Common Applications:

  • Window Profiles
  • Fencing
  • Decking
  • Railing
